Oh, THIS one is fun :) It's around 15 minutes of play time on average
speed, but it's very, very high intensity play.

Forces are going to come at you from all sides. I put a batch of units on each
of the four sides of the ships - larger forces by the gates to the north and
south, smaller ones on each side. I also sent a reasonable force of units through
the north gate, around to the east and up on the ridge. They picked off the
REALLY annoying guys that hang out up there.

Make sure you have medics in each group, and make sure you protect them!

Watch out for Sub APCs - they pop up right next to the ship itself. That's why
you need the two groups immediately beside the ship. Other than that, repair
your turrets and just stay alert for intruders. It requires a lot of watching
and waiting, but it's really not that hard to win this one.
